My point was simply that at warp, when the ship is heading in a particular direction, the only degree of freedom in the orientation of the ship is in the roll angle.

Similar remarks apply at impulse...

In regards to TOS and TOS movies, where the ship is pointing and where the ship is going do not need to be the same. There are times where the Enterprise at warp and impulse keeps her nose at a target while traveling in a different direction. ("Elaan of Troyius", "Balance of Terror", "The Corbomite Maneuver", "The Motion Picture", "The Wrath of Khan", "The Search for Spock" come to mind.)

Now with that said, the Enterprise appears to prefer accelerating going forward or backward but once moving, has no problem pointing away from where she's going.
